RHEOLOGICAL MECHANICS MODEL OF SHEAR RATE THICKENING THE BEHMIOR OF SEMISOLID SLURRISS
剪切速率增稠半固态合金浆料的流变力学模型

The constitutive behavior of semisolid slumes depends on a number of macroscopic factors. These factors translate to internal variables and external variables that govern the rheological behavior of the material. Internal variables include a measure of the degree of agglomeration among solid pericles, fluid phase viscosity, particle size, particle morphology, and distribution of particle sizes. External variables are temperature and shear rate. According to the different characters of semisolid slurries, we can give the corresponding new models under the different conditions on the basis of the primary models.
